Security Windows 7

Hey guys sorry to be a pain but just one last question about my security for my desktop running Windows 7. I have a paid version of Avast till Feb 2015 and my browsers are firefox for online banking and Opera for my forums and windows shopping ebay, tigerdirect etc and my bills are on Opera because I like the app you click on what you want to visit
I also run in firefox for my banking is Trustee Rapport and thats it am I missing something or am I good
Once in awhile I clear my history but I don't download on this I use my laptop for downloading .

thanks guys

I would add the obvious things here.

Always use a standard account for normal use, leaving an admin account only for doing admin-only things.
Use a firewall, with a proper set of very restrictive rules.
Use common sense! Take caution when downloading things from unknown sites, strange emails, dubious websites and the like. More often than not, the problem is that the user himself does something that he should not do.
Make sure you do frequent backups of all important data, just in case. Not only for security, but also in case of hardware failures.

Here is also a more advanced guide on the matter, to make Windows really safe: http://hardenwindows7forsecurity.com...tandalone.html
